More than a year after Cephalon Inc. merged into Teva Pharmaceutical Industries, the former’s general counsel has returned to private law firm life.

Jerry Pappert, former Pennsylvania attorney general and current chairman of the Pennsylvania Banking and Securities Commission, has joined Cozen O’Connor’s commercial litigation group as a shareholder in Philadelphia. The former Cephalon general counsel will also be working closely with Cozen O’Connor Public Strategies, the firm’s government relations arm, Cozen O’Connor said Monday.
